RIGGING AND ELECTRICAL SAFETY
IMPORTANT: The loudspeakers described in this manual are
designed and intended to be mounted to diering building
surfaces using a variety of rigging hardware, means and
methods. Installation of loudspeakers should only be performed
by trained and qualied personnel. All electrical connections
must conform to applicable city, county, state, and national
(NEC) electrical codes.
. DANGER: It is possible to experience severe electrical shock
from a power amplier. Always make sure that all power
ampliers are in the "OFF" position and unplugged from an AC
Mains supply before performing electrical work.
IMPORTANT: Refer to the sections on installation and
connections later in this manual for additional information on
rigging and electrical safety.

IMPORTANT: Please review the safety guide accompanying
this product and these installation instructions prior to
installing this loudspeaker.
CAUTION: Installation of Biamp loudspeakers should only be
performed by trained and qualied personnel. It is strongly
recommended that a licensed and certied professional
structural engineer approve the mounting. Severe injury and/
or loss of life may occur if this product is improperly installed.
DANGER: It is advised that a safety cable be secured to a
suitable load-bearing point separate from the primary
loudspeaker mounting point, with as little slack as possible so
as not to develop undue kinetic force if the primary mount
were to fail.
IMPORTANT: This loudspeaker is approved for use in plenum
air handling spaces.
INSTALLATION
The CM10TB ceiling loudspeaker is designed to be installed with or without
above ceiling access in drop ceilings. Prewiring and installation of optional New
Construction Bracket (SPA-NC100) allows the loudspeaker to be installed in new
drywall ceilings. CM10TB loudspeakers can be mounted in larger pre-existing
cutouts using optional ceiling trim rings (SPA-TR100).
Once the loudspeaker is mounted, rotate the face-mounted tap switch to select
the appropriate tap setting before any audio is passed through the loudspeaker.
Do not change the setting on the tap switch while the loudspeaker is in use.
Installation in drop (suspended) ceiling (typical)
1. Run wires to the loudspeaker locations.
2. Remove the ceiling tile and use the template to cut a hole in the center of
the tile. Remove any debris from around the hole.
3. Place the tile rails on the grid, and t the spacers onto the rails. (Ceiling
grid not shown).
4. Reinstall the ceiling tile and align tile rails on either side of the opening.

NOTE: All electrical installation
connections for loudspeaker
lines are subject to all
applicable governmental building and
re codes. The selection of appropriate
electrical hardware to interface with the
loudspeaker lies solely with the
installation professional. Biamp
recommends that an appropriately
licensed engineer, electrician, or other
professional identify and select the
appropriate conduit, ttings, wire, etc. for
the installation.

Installation in a drop (suspended) ceiling with conduit
Prepare the ceiling tile as shown above. Access to the loudspeaker through an adjacent tile space is necessary to attach
the conduit after the unit is installed in the ceiling tile. The included wiring cover has two knockouts on the top to fit 1/2"
and 3/4" NPT conduit (22mm [.875"], 29mm [1.14"]). Conduit fittings are not included. Use flexible conduit close to the
loudspeaker to make alignment and connections easier. Run wires and conduit to the loudspeaker locations.
NOTE: Conduit use may be required for some plenum spaces and should also be used in damp spaces. Using the cover
with conduit wiring will comply with the City of Chicago requirements.

INSTALLATION (CONTINUED)
Wire the loudspeaker
The cover acts as a strain relief for wiring connections. This can be accomplished
in 2 ways; sandwiching the wires between the cover and the foam on the side of
the input area, or using a cable clamp or conduit fitting in the knockout and routing
the wiring through it. The second option is described in the grey box on the bottom
of the next page.
1. Loosen the screws (circled) holding the cover enough to allow it to move.
2. Move the cover up to clear the lower screws and rotate it around to expose
the euroblock socket.

6. *Secure a safety cable to the safety tab on the cover. Attach the cable to a
secondary structural point directly above the seismic safety tab to minimize
impact force and swing in the event of a ceiling failure. Make the cable as
short as possible.
*NOTE: This can also be done after installing the unit if there is access in
the ceiling.

Cable Clamp or Conduit Applications - Input Cover
1. Remove the cover by unscrewing the center screw.
2. Remove the cover knockout and install a cable clamp or conduit tting
(not included). For conduit applications, using exible conduit at the
loudspeaker location is recommended for easier installation.
3. Thread the cable or wires through the clamp (or tting) and wire the
euroblock connector as shown. Loudspeakers may be daisy-chained by
using the second set of terminals.
4. Re-install the cover and secure. If using a cable clamp, tighten the clamp
screws around the cable to provide strain relief.

INSTALLATION OPTIONS
Installation in a drywall [sheet rock] ceiling
Adequate distance above the drywall should be available to accommodate the
depth of the back can.
1. New construction brackets (SPA-NC100) should be utilized and secured to
the ceiling structure.
NOTE: Use a stretched string or laser to align the brackets, rather than
aligning to the truss.
2. Run wiring to each bracket location allowing sucient length to allow for
connection to the back can. There is a cleat to secure the wiring to keep it
accessible at the hole location.
3. A safety cable should be attached to the structure with sucient length to
allow for connection to the back can. Make it as short as possible while still
allowing for connection before loudspeaker installation.
4. Install the drywall and cut out the hole inside the bracket. Allow wires and
cable to hang through the hole or be accessible in the ceiling
5. After the ceiling is nished, install the loudspeaker (steps 1-8 of this guide
- pages 4-6). Screwing down the clamps will secure the loudspeaker in the
ceiling.
6. Finish the installation by setting the tap switch and installing the grille
(steps 9-10 - page 7).
